PADLOOK.

SPECIFICATION forming part of Letters Patent No. 298,476, dated May 13, 1884.

Application filed March 7, 1884.

T at whom it may concern:

Be it known that I, CHARLES W. J UDsoN, of Terryville,'Litchfie1d county, Connecticut, have invented a new and Improved Padlock,

of which the following is a full, clear, and exact description.

The invention consists in certain improvements in padlocks, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal view of 1nyin1- proved lock, one side of the casing being removed, the shackle being locked in the casing. Fig. 2 is a like view, the shackle being unlocked. Fig. 3 is a sectional plan view on the line or m, Fig. 1. Fig. 4 is a sectional plan view on the line y 1 Fig. 2.

The flat lock-casing Ais provided in its top with two apertures for the two ends of the shackle B, the prong B of which is longer-than the prong B". When the end of the prong B is on the bottom of the casing, the end of the prong B projects slightly into the top of the casing. The prong B is provided with two opposite notches, C, adapted to receive the ends of a V-shaped spring, D, resting on a horizontal partition, E, provided with a slot, E, for the key F. The key, if inserted in the casing, passes in between the prongs of the spring D, and if the key is turned on its vlougitudinal axis, it separates the ends of the spring D and presses them out of the notches C, thus permitting the shackle to be swung in such a manner that the prong B turns on its longitudinal axis. The prong B is provided, a short distance below the top of the casing,

0 with an annular groove, G, which presses the (N0 mod e1.)

forked free end of a fiat spring, H, held at its opposite end in the lock-casing, a short distance below the top, by side lugs, H, passing into apertures of the casing, the free end of the spring H pressing upward. I 5

The operationis as follows: Whentheshackle is held in the lock, it is in the position shown in Fig. 1, the shackle being held in the casing by the ends of the springs D, whichare in the notches C. If the key is turned in the casing, the ends of the spring are withdrawn out of the notches C, thus releasing the prong B of theshackle. ThespringHiinmediately-throws the shackle upward, whereby the end of the prong B is withdrawn from the top of the casing and can swing to one side. The spring H also prevents withdrawing the prong B entirely from the casing, as the free end of the spring is in the annular groove in the prong B. Having thus describedniy invention, I claim as new and desire to secure by Letters Patent 1. The combinati0n,with a lock-casing, ot'a shackle having an annular groove, and a spring held at one end in the casing a short distance .from the top, which spring has its opposite free end forked and passed into an annular groove in the shackle, substantially as herein shown and described.

2. The combination, with a lock-casing, of the shackle B,'having an annular groove, G, and the fiat spring H, having one end forked and pressed into the groove G, and provided at the opposite end with two side lugs, H, passing into apertures in the sides of the casing, substantially as herein shown and described.
